Parallel communication library for TCP stack

Abstract

Message Passing Interface (MPI) has been the predominant standard for writing parallel applications. MPI allows programmerss to write a parallel application by handling the communication between a set of processes. The proprietary high performance network, along with the basic functionalities, may provide additional functionalities or may be able to handle some of the MPI functionalities. There is need to change or modify MPI library in order to validate additional functionalities that the network supports. We plan to implement parallel communication library (PCL) that can provide MPI like interface to the user and simultaneously make use of the additional features provided by the underlying network. The focus of our work is not to implement all the features that MPI provides for the application, but to implement minimal functionality of MPI and employ the additional features that the underlying network interconnect provides. Before targeting the proprietary network, we have developed parallel communication library for standard TCP stack as a part of the first stage of our project. We have implemented a few basic functions in parallel communication library. In this paper, we would like to share our work with the community. Also, we have evaluated the PCL for standard TCP stack using basic tests. We present the performance results of those basic tests.
